Increase energy efficiency by up to 20% while providing superior protection and appearance! Our coating is durable, flexible, and aesthetically beautiful. Suber by Kolmer is a breathable weather-water barrier & insulator in one envelope system. It will quickly protect and increase the value of your building while dramatically lowering construction, lifetime maintenance, & energy costs.

SUBER by Kolmer™

is a patented exterior coating system manufactured from 96% high-grade raw cork and a proprietary highly adhesive water-based acrylic resin. It has superior thermal and acoustic insulative properties, is UV resistant, and impervious to wind-driven rain while maintaining healthy water-vapor transmission. This unique combination allows for optimal protection of the substrate while permitting natural curing to occur. Naturally, cork is deterrent to insects, mold or mildew growth, fire retardant, and is a 100% renewable natural resource.

SUBER by Kolmer™ has an extremely low thermal conductivity property, deterring heat and cold buildup, allowing the coating to remain comfortable to the touch in extreme environmental conditions. This attribute contributes significantly to an average of 15-25% energy savings.

Aesthetically, our system presents a consistent surface appearance with superior adhesion directly to substrates with minimal preparation. Unlike stucco, EIFS, and other rigid coatings, it is highly resistant to surface cracking due to its characteristic of remaining pliable and expandable.

SUBER by Kolmer™ is offered in a full range of integral, ultra UV resistant color choices, eliminating the need for post application field painting, thus reducing application labor expense and cycle time of project completion. If desired, the coating can be field painted as well.

" I’m excited about the versatility and protection Suber offers. Along with a great look, it brings a unique value over options available to architects until now... "
